|
Ans:B. Maturation of synthesized protein
Structures shown in the image:
1= Nuclear membrane; 2= Nuclear pore; 3= Nucleolus;4= endoplasmic reticulum; 5= Golgi body; 6=Mitochondria; 7= Microtubule; 8= Lysosome; 9=Vacuole; 10= Plasma membrane
Organelle Function
- Nucleus : DNA replication, transcription.
- Endoplasmic reticulum :lipoproteins, drug metabolism, ethanol oxidation Biosynthesis of proteins, glycoproteins,, synthesis of cholesterol (partial).
- Golgi body : Maturation of synthesized protein
- Lysosome : Degradation of proteins, carbohydrates, lipids and nucleotides
- Mitochondria : Electron transport chain, ATP generation,TCA cycle, beta oxidation of fatty acids,ketone body production, urea synthesis(part), heme synthesis (part), gluconeogenesis(part), pyrimidine synthesis (part)
- Cytosol : Protein synthesis, glycolysis, glycogen metabolism, HMP shunt pathway, transaminations, fatty acid synthesis, cholesterol synthesis, heme synthesis (part), urea synthesis (part), pyrimidine synthesis (part), purine synthesis
